The Corrosion and Protection of 20# Steel in Adopted Liquid of ASP Flooding Weak Alkali System

The corrosion of 20# steel in adopted liquid of ASP(Alkali/Surfactant/Polymer) flooding weak alkali system was studied and the specimens were examined using scanning electron microscopy.In the simulated liquid,with the increase in concentrations of three components,the corrosion rate increased.The static simulation testing,dynamic loop test and field test showed that the corrosion protection properties of epoxy coating in ASP was relatively good.
